Definitions
- the present invention relates to a surface treatment method for the sensing thin-film, particularly to a surface treatment method by using the NH 3 plasma treatment to modify the sensing thin-film.
- the enzyme has been widely applied in various fields of industrial production and inspection at present.
- the enzyme is one of proteins.
- the protein is composed of the amino acids arranged in long chain and folded into certain shape. Thus, it has various activity or function.
- the amino acid sequence of enzyme is changed, the activity or other properties of enzyme can be changed.
